l. l., 1 l l 1 l fr w/r/vEssEs Tt .azz whoma may mem-lspecification Beit -known that,I,-EnwARD.1RussnLL, a' Subiectnofthe King of Great Britain, and a .resident vof-tliecity of New lYorlgborough of. Brooklyn, in the county Vof Kings and State of New York, havefinvented'a new i and Improved Liquid-Cooler, of which the to minimize the transmission of heat from following isa full,'clear,'and 'exact description.

. This invention relates to liquid coolers -and morefparticularly `to a lcooler for drinking water, beer and other fiuids," whicli 'has hollov'sr walls constituting vacuum' chambers the outer air to a receptacle serving as a container .for -a refrigerating substance, such asl 1ce,'and itself forming al vacuum chamber, so. that the refrigerating s ubstance is contained 1n a vacuum and `1s .surrounded by vacuumchambers.

An object'of-the invention 1s to provide Aa simple and inexpensive cooler-for iuids of soy various-kinds, in which ice or other refrigerating substance iscontainedina vacuum and 1s surrounded by vacuum chambers, to mini-y inize the .melting of the refrigerating-substance, *owing to the transmission chamber, Iund which has-means for conducting the fluid to be cooled, through the refrigerating chamber.

'A further object of the invention is to provide a device of the class described in which the ice orother refrigerant is contained in a vacuum chamber, the Walls of which constitute further vacuum chambers to insulate the refrigerant thoroughly from the outside atmosphere, in which t-he refrigerant container has a removable cover to permit of the introduction of the refrigerant, `.the cover itself, constituting a vacuum chamber, and which is provided further with a pump for exhausting the. air'froin the con-A tainer.

Beire proceeding to amore detailed eX- planation of my invention, it should .be clearly understood that While the same is particularly usefulv in cooling Water, .beer and other otable liquids, it'. can also be adlvantageou y employedffor cooling'or refrigerating otheriuids. For example, the device can `be used in. certain chemical operationsffor cooling gases or for condensing .65 gases. :L

It is well known that the vacuum consti# tutes one of the best known insulators aaainst onsequently,-I provide a vrefrigerant container, the top, the bott-oni and theside walls of twhich constitute vacuum chambers to. prevent the heat of the .surrounding atmosphere from penetrating .to the refrigerant and causing the same to melt rapidl In order 76 to preserve the4 refrigerant. as? ong as pssible I provide means for exhausting the air within the container,`s`o that the `refrigerant,- Which may consist of ice, cooled brine yor any other suitable substance,4 is not only 80 surrounded by vacuum chambers,biit is actually located in a4 partial vacuum. f

Referring more particularly tothe draw ings, in the form ofthe vdevice shown in Figs. 1 and 2, I provide a substantially c 85 .lindrical container 10, the bottom'll-and t e sides l12 of Whicli'are' double and form a continuous vacuum chamber 13. Braces 14 arci located between lthe double walls ofthe lbottom aiid the sides, .toprevent the collapse Vof the same, owing to the pressure of the outside air.' It vill be understoodthat theV i device may be fashioned from anysuitable material, preferably from sheet metal. 'At the outside, the container is covered with a 9`5 layer of Vheat insulating material 15 sueli'as asbestos fabric -orthe like. 'Above the bottom 11. of the container and spaced there- 'l from, is arranged a door` lowhich-serves; to

support a block of ice 17 or any other refrigloo erant. A cock 18 is located at the side ofthe container. and.' has'v a stem, 19j-f extending l throu h'suitable openin of the sidewalls into t espace between t e'oorllGj and thel :bottom 14. Af pipe '20 extends upwardl 166 from the. doorv 16 'and communicates wit the space/betweenthe latter and the bottom.

.of an embohimentfwof my inventiony'f'and At the upper rim, the sidewalls ofthe `container have substantially parallel, .u `wardly extending -fla'nges 21', between wliici is located an annular gasket or washer 22, consis'ting preferablyrof a ring of rubber, of

circular cross-section. VA cover 23 is' mounted upon the upper rim of the container and' seats uponthe Washer. The cover is double,

.and has a vacuum chamber 24 formed therein. Spring keepers. 25 are mounted upon the sides of the container and are arranged to engage detents 26 Vcarried by the cover, whereby the latterv can be secured and held in position upon the container, an air-tight joint being formed b the gasket 22. Upon the covcr is\mounte an upwardly tapered casino' 2 7*l aving a substantially central, in-

wardly .air downwardly inclined iange 28 arranged to receive and support an inverted y waterbottle 29 -or other similarly formed liquid container.V The neck 30a ofthe bottle projects into' the casing 27, which conseuently fills with liquid fnom the bottle 29.

he cover has an outlet pipe 30 extending therethrou h into the container 10 and arranged toi ioned from rubber or other resilient material and carried at the upperend of the ipe 20,

. whereby communication is effected etween .the interior ofthe casing 27 and the space between the bottom V14: andthe floor 16 of the container.

I provide an airl pum 3.2 twhich may be of any suitableform an yhas a pipe 33 extending through suitable o enings in the side of the container so that t e air can be exliausted from-within the`container by means of the pump. After the ice or other refrig erant has been placed in the container the cover is secured upon the same and a bottle is inverted and placed upon the su porting casing 27. The liquid will lovg rom the bottle, throughthe outlet 30 and the ipe 20 into the space under the floor 16, w ere Vit e received. by a socket 31 fash-V will be cooled bythe refrigerant. It can be withdrawn from the container by means of tlie cock 18, as desired. The air is exhausted from within thcontainer by means' of the air pump, so th located in a vacuum.

It may be found unnecessary to -provide the covers for the container, with vacuum chambers and in that case the covers4 may consist o simple plates, or be of any other suitable form.

I wish to'emphasize that my invention does 'not' reside incertain of the details of construction illustrated herewith, but con-- the refrigerant is actually Having thus described my invention, I

claim as new, and desire to secure by Letters f In a device of the class described, a receptacle for a refrigerant, a removable cover` carried by said receptacle and rovided with' means for supporting a iui container, a com Jartment in said receptacle, a pipe extenr ing toward said cover and communicatinglwith said com artment, said pipe. haviiiga socket of'resilient material at the free 4end, and an'outlet pipe carried by said cover and removably received by said socket.

In testimony whereof I have signed my name to this specification in theV presence of-- two subscribing witnesses.
